Answer - A designer primarily faces two major problems while implementing a network-transparent system. They are as follows: - The primary problem is to make all the processors and storage devices to appear transparent on the network. This implies that the distributed system should appear as a single centralized system to the users using the network. There are two solutions to it: - The Andrews files system - The NFS system. - Both these file systems (distributed) appear as a single file system to the user whereas in reality it may be distributed over the network. - The secondary issue is regarding the user mobility. The designer would want any user to connect to the entire system overall rather than to a particular machine.
